I am setting up S5D9 as default gateway for ethernet network and a custom wireless network connects S5D9 to internet which is seperate from ethernet network. I have added DHCP server for ethernet on S5D9 which is able to assign IP address to clients. Now if some clients wants to do TCP/IP connection to outside world, which port should i listen to on the S5D9 ? I have set Default Gateway IP address in DHCP settings (192.168.0.1) but there is no default port number. In the real application i have no information or control on clients behavior except that it has DHCP client, it gets IP address from S5D9 and it communicates with a server on global network using TCP/IP?
Any suggestions on which TCP socket should i create on S5D9 and what should be its port number?
THanks
